My PS3 currently doesn't have access to the internet. When I purchased Tom Clancy's Las Vegas it updated my PS3 to Version 1.7. I recently downloaded update 1.82 from the official site and installed it by USB. This may be a stupid question, but should I have installed version 1.6, version 1.8, etc. first and by doing it as outlined above, am I missing data, etc. Thanks.
